Benefits of pre-emptive analgesia by local infiltration at day-case general anaesthetic open inguinal hernioplasty.

Introduction The open prosthetic repair of inguinal hernias under local anaesthesia (LA) is well established, with the concept of intraoperative 'pre-emptive analgesia' evolving so that patients are as comfortable as possible. We used a peri-incisional LA solution in patients undergoing day-case inguinal hernioplasty under general anaesthesia (GA) and recorded use of analgesia in the immediate postoperative period. Methods In this observational cohort study, 100 consecutive unselected men underwent open inguinal hernia repair as a day case. Of these, 75 underwent repair under GA and 25 with peri-incisional LA solution (equal mixture of 0.5% bupivacaine and 1% lignocaine with 1:200,000 adrenaline). Analgesia prescribed at induction, for maintenance and after cessation of anaesthesia was scored in accordance with the World Health Organization (WHO) analgesic ladder. Results The median age in the GA group was 59 years (range: 25-89 years) and in the GA+LA group, it was 62 years (range: 27-88 years). Of the 100 patients, 82 underwent a mesh plug repair by seven surgeons whereas 18 underwent a flat (Lichtenstein) mesh repair by two surgeons. WHO analgesic induction and postoperative scores were significantly lower in the GA+LA group (p=0.034 and p<0.001 respectively). There was also a significant difference in use of postoperative antiemetics (23% vs 0% in the GA only and GA+LA cohorts respectively, p=0.020). Six patients (8%) in the GA group failed day-case discharge criteria. Conclusions Patients undergoing contemporary day-case GA inguinal hernioplasty with pre-emptive LA solution infiltration require lower levels of postoperative opioid analgesia and antiemetics. These cases are less likely to fail discharge criteria for planned day surgery.

The value of auditing negative lower GI investigations preceding a final diagnosis of colorectal cancer.

OBJECTIVE: To review all preceding 'negative' large bowel investigations in patients with a final diagnosis of colorectal cancer, and to examine whether delayed diagnosis was associated with worse outcome. METHOD: Details were gathered on all patients with a new diagnosis of colorectal adenocarcinoma presenting over 4.5 years. For each patient the hospital's clinical workstation and radiology and endoscopy databases were interrogated for all flexible sigmoidoscopies, colonoscopies and barium enemas during the 5 years prior to diagnosis. RESULTS: Among the 570 patients, 28 (5%) had undergone colonoscopy and/or flexible sigmoidoscopy that had not shown colorectal cancer during the 5 years preceding final diagnosis, and a further 28 (5%) had undergone 'negative' barium enemas. Polyp surveillance might have missed four lesions destined to become malignant. Correspondingly there were three patients undergoing IBD surveillance found to have CRC, having had a negative complete colonoscopy within the preceding 5 years. Among patients undergoing de novo colonoscopy for diagnosis the true miss rate was only one patient per year. At August 2007, 29 (58%) of those with delayed diagnosis were still alive, compared with 216 (42%) of those diagnosed during initial investigation (chi2 = 5.04, P < 0.05). CONCLUSIONS: Colonoscopic miss rates are in line with previous studies. The application of simple clinical ground rules will avoid most pitfalls. The methodology described herein may assist in auditing the quality assurance of lower gastrointestinal diagnostic services. Despite the delay, late diagnosis was found to be associated with improved survival and a lower likelihood of metastatic disease.

Ogilvie's syndrome: a new approach to an old problem.

PURPOSE: This study was designed to determine the value of intravenous neostigmine in achieving adequate colonic decompression in patients with Ogilvie's syndrome. METHODS: A prospective study was undertaken in 12 consecutive patients (median age, 60 (range, 38-98) years) with contrast enema-proven Ogilvie's syndrome (median duration, four (range, two-nine) days) RESULTS: Satisfactory clinical decompression of large bowel distention was attained in 11 patients, although one required colectomy for subsequent recurrence and ischemia. CONCLUSION: These results support the theory that many cases of Ogilvie's syndrome are the result of excessive large bowel parasympathetic suppression rather than sympathetic overactivity.

The role of total thyroidectomy in the management of differentiated thyroid cancer.

The extent of surgical resection required in the optimal management of differentiated (papillary and follicular) thyroid carcinoma remains controversial. Arguments in favor of total thyroidectomy include the adequate treatment of tumor multifocality, reduction in local recurrence rates and anaplastic transformation, and creating a suitable environment for radioactive iodine scanning and treatment of metastases. The benefits of this procedure have to be weighed against the potential but minimal morbidity.
